Swarm volumes can be replaced after either an admin-initiated Retire (see Managing Chassis and Disks) or a Swarm-initiated failure resulting from I/O errors (see Retiring Volumes). After a volume is marked either Retired or Unavailable, it can be replaced.
Administrators can insert a drive into a running node without restarting the server, provided the server hardware supports this function and disk.volumes = all is configured. This feature (called hot plugging or hot swapping) allows adding storage capacity to a node at any time.

Swarm UI: In the Swarm UI, administrators can suspend an in-process volume recovery using the Suspend Recovery option under the settings (gear) icon. After the drive is replaced, resume the recovery using either the Enable Disk Recovery button in the banner message or the Enable Recovery under the settings gear icon.
Info title Tip For drive-related events requiring user action (such as drive removal), Swarm helps locate the hardware by including the SCSI locator (bus ID) and volume serial number in the log message displayed in the UI. (v9.2)
